This is the kind of work I do at my day job.

I enjoy making the home movies more.  I get to do whatever I feel like doing.  I get to explore whatever techniques I want to try out.  It’s a natural extension of my creative energy!

This short movie illustrates how you can get creative with your own movies.

I took simple footage from my consumer camcorder and motion tracked my mouth onto it.

In your version it doesn’t have to be so elaborate.  You can just draw a mouth onto your finger and get a similar effect.
